Tire sizes: difference between 155/80R13 and 155R13?

ratio and '13' the wheel size in inch. But how come sometimes the aspect
ratio is omitted? Does that mean "aspect ratio not important", or maybe
in smaller tires (I've only noticed this omission in smaller tires) the
aspect ratio doesn't vary much? Thanks for enlightening me - I have
looked into all kinds of car books, and the FAQ here, and never found
an explanation for this.

Yes it can be a good tire. I've run into this a couple of times with
my SO's old Merc and our present Vanagon both run a 184R14 tire. I
think it's just how tires were sized before aspect ratio became important,
but I'm not sure. I ask a tire guy once for a 185/80 R14 for the Van and
he said there was no such size for it and that the 185R14's ratio was
not really 80 (it was close - he said he was spliting hairs). So yes
the 80 may be omited but it may very well be a good tire. I mean I can
get a number of different tires from different companies all sized 185R14
and all good (or great) tires (Mich, Conti, Yoko, Brig...you name it).

If no ratio is stated, it is a default of 80 (on the P-Metric
system).
On the old bias tires, it used to be a default of 78. Most of
the little jap-boxes came with tires that just said 145/13, or 165/13,
ect.

identical to the original one, except that it has an extra lead next
to the lead that energizes the solenoid. Unpowered, it doesn't
appear to make any electrical connection to any other lead or case. I
will probably just ignore it, but does anyone have a guess of its
purpose?
Thanks in advance.

during cranking; it gives a hotter spark than you might get with a low
battery voltage and the resistor in place. During normal running with
the battery up the resistor sets the coil maximum current.

when the solenoid is energized, is fed from the battery supply. This is used
to supply power directly to the ignition coil only when cranking. This bypasses
any ignition resistors and supplies full battery power to the coil when
cranking loads usually reduce its voltage. When not energized, this terminal
will look like an open circuit.
Or I may have no idea what I'm talking about :-)

If it's the starter cylinoid then the extra terminal is probably a
neutral starter safety switch. This prevents you from starting your
car in gear, which normally you don't want to do :) If it's the
starter MOTOR, i.e. the starter, then it should only have one lead
which is off from the starter cylinoid.
If your car starts fine then don't worry about it, no problems
will result from leaving it unhooked from anything.

The extra terminal off of the cylinoid is usually the accessory power
source. (It should be "hot" when the key is on, but the starter is not
engaged.) This is used by some auto systems to kill power to radios,
power windows, etc. while cranking the engine.
